| 摘 要： | 钢渣常被当成工业废弃物处置,但其碱性强、棱角丰富,兼具有优异的力学特性,可以改善沥青混凝土的抗水损害、抗高温变形以及耐磨和抗滑等性能,被认为是可替代天然矿质集料的理想筑路材料。近年来道路建设对集料用量的高需求与天然集料短缺之间的矛盾越来越突出,钢渣沥青混凝土技术因而成为备受关注的热点。概述了钢渣的材料特性以及钢渣沥青混凝土的设计与性能,介绍了钢渣沥青混凝土的实际应用情况,研究了钢渣沥青混凝土长期应用后的路面性能变化,最后对钢渣沥青混凝土未来的发展趋势进行了展望。

| Abstract: | Steel slag, an industrial waste with strong alkalinity, rich angularity and excellent mechanical properties, can improve performances of asphalt mixture such as moisture stability, high-temperature deformation resistance, abrasion and skid resis-tance. Therefore steel slag is considered an ideal alternative to natural mineral aggregate. In recent years, the contradiction between the urgent demand for aggregate in road construction and the shortage of natural resource is becoming acute. So the use of steel slag in asphalt mixture has attracted more and more concern. This article first outlines the material characteristics of steel slag, and the design and performance of steel slag based asphalt mixture. Then the engineering application of steel slag based asphalt mixture is introduced. The change of pavement performance during long period using is also presented. Finally, the future development trend of the technique of steel slag asphalt mixture is forecasted. |
